Babies with high fever can take warm baths, especially for babies under 3 months of age, as this age group usually cannot use any fever-reducing medication. 3-24 months old babies can also take warm baths, and the cooling effect can be maintained for a short period of time, while the cooling effect of medication can be maintained for up to 4-6 hours. If your baby has a fever of 38.5°C or higher, you should take fever-reducing medication to avoid febrile convulsions, and you can use fever-reducing medication such as ibuprofen granules or acetaminophen suspension. After taking the medicine can not immediately play the effect of reducing fever, this time to the baby to take a warm bath can assist in cooling. One hour after taking the medicine to play its maximum role, the body temperature can drop more than 1 ℃, so it is safer. Other physical cooling methods include wiping the neck, armpits, groin and other large blood vessels with warm water, and you can also give your baby a cooling patch, but the effect of reducing fever is relatively mild and suitable for smaller babies.
